There are many areas with small submarine volcanoes, which are important feeding zones for marine birds and mammals. The submarine area of Galapagos (from 0 to 590 feet deep) is of 2.587 square miles. Here's More Galapagos Islands information

The uniqueness of the Galapagos Islands is largely due to the remoteness of the Archipelago which has never been connected to the lands of the South American continent.

Also the Islands were declared a National Park in 1936 to preserve the flora and fauna of the 13 large Islands, 6 minor ones and more than 40 islets. The origin of the Galapagos Islands is volcanic.

These volcanic Islands are around 4 to 5 million years old, making them quite young in comparison to the Earth.

Washed by tropical waters of the Panama Current from the north and the cold, nutrient-rich waters of the Humboldt Current from the south plus the Cromwell Current from the west, the Galapagos marine reserve has an amazing diversity of sea life.
